Answer:
x = 1 3/5
Step-by-step explanation:
distribute.
-2.5*4x + (-2.5*-4) = -6
-10x +10 = -6
subtract 10 on both sides
-10x = -6 -10
divide by -10
x = -16/-10
x = 1 3/5
Answer:

Step-by-step explanation:
In
,
represents a constant related to the period of the function. Here's how it's related:
, where
is the period of the function.
We're given
, so solving for
:

3x - 6y = 20
-6y = -3x + 20
y = 1/2x - 20/6.....slope = 1/2...y int = -20/6 = -10/3
2x - 4y = 3
-4y = -2x + 3
y = 1/2x - 3/4..slope = 1/2...y int = -3/4
same slope, different y int = parallel lines = no solution = inconsistent
Answer:
AC and DF
Step-by-step explanation:
We can see that the triangles have a scale factor of 3.
1 * 3 = 3 (AB and DE)
2 * 3 = 6 (BC and EF)
However...
2 * 3 = 6 not 7 (AC and DF)
